# Composal vs Chromatic

By Composal. Sources reviewed: 2026-10-15.

Chromatic derives coverage from Storybook stories and reviews whether component rendering changed.

## Composal

Composal sends AI browser agents to use your running web app and check the outcomes you care about. Define journeys as plain-English Scenarios, map existing flows with Discovery, or explore for bugs with Deep Scan. Runs keep recordings and reproduction steps so your team or coding agent can investigate a Finding.

## Chromatic

Storybook visual testing and UI review

Chromatic turns Storybook stories into visual tests, rendering component states in cloud browsers and comparing snapshots with accepted baselines.

## Where each fits

Choose Chromatic when Storybook is central to your design-system workflow and you want visual and UI checks tied to stories and pull requests.

## Try this evaluation

Select a shared component with several Storybook states and one user journey that combines it with navigation and form behavior. Introduce a subtle visual change in one story and a separate interaction regression in the full application.

### Coverage

Which user outcomes must this release prove, and which specialist checks must stay in your existing stack?

### Setup

Who prepares accounts, test data, permissions and access to the deployment being tested?

### Evidence

Can the engineer reproduce a reported failure from the recording and steps, without asking the tester to investigate again?

### Ownership

Who updates the checks when the product changes, and can the team review what a passing result actually proves?
